摘要
X-射线衍射是表征材料结构的一类重要技术,在材料化学教学中具有举足轻重的地位。随着新型材料的不断发现,相应的先进X-射线衍射技术也应运而生。本文基于当前材料化学学科前沿,对高压同步辐射X-射线衍射技术、微焦斑X-射线衍射技术和同步辐射X-射线对分布函数三种先进技术进行介绍,旨在加深学生理解X-射线衍射相关基础知识的同时,能够拓宽科研视野,并提高解决问题的能力。
X-ray diffraction is a pivotal technique for material structure analysis,playing a fundamental role in materials chemistry.In light of the continuous discovery of novel materials,advanced X-ray diffraction methods have emerged at the forefront of materials chemistry.This paper introduces a teaching reform incorporating three advanced X-ray techniques into materials chemistry instruction:high-pressure synchrotron X-ray diffraction,micro-focus X-ray diffraction,and X-ray pair distribution function analysis.We anticipate that such a teaching reform will empower students to deepen their grasp of X-ray diffraction techniques,broaden their academic horizons,and refine their problem-solving skills.
